Does electrical Grid operational analogy helps ?Re: Grid EconomicBrokering Architecture WG

[Rajkumar Buyya <raj@cs.mu.OZ.AU>]

Dear All,

We (a colleague of mine and I) have made an attempt to compare and
contrast key elements of electrical and computational grids. In the recent
past, a lot of interest in Grid economy and scheduling is getting
generated, so I thought some of you may be interested in our article. I
guess understanding of operational model of regulated and unregulated
electrical grids might of great interest in order to realise economic
efficiancy. You may want to browse the article:
   http://www.buyya.com/papers/WeavingGrid.pdf

It does investigates/brings out different economic models used within
electrical grids that are used to realise power distribution, load
balancing, and economic efficiancy. There are some thoughts on how we
might realise such system within our computational grids.

Comments are welcome.

The plan sounds good. I am happy to involve actively and contribute to the
community effort. Nimrod-G is one of the early works/implementations of
economic-driven grid scheduling. Yes, this was developed using Globus
services. I guess, it will be useful to look into this and build on.

On related matter: Scheduling studies does require detailed evaluation
efforts. Towards this, we have developed a grid modelling and simulation
toolkit called GridSim (, which is done as part of the Gridbus project).
Since GridSim is open-source and community driven effort, I am happy to
extend it (or we all can do it jointly) to meet the needs of this new WG.
More information about (pointer to) GridSim can be found at:

Suggestions, comments, etc. are welcome.

Thanks
Raj
